REP Renewable Energy Technologies & Applications

Question 1

What is a primary benefit of using solar photovoltaic (PV) systems?

Accepted Answer

They provide renewable, clean energy with minimal emissions

Answer

A primary benefit of solar photovoltaic (PV) systems is their ability to provide renewable, clean energy with minimal emissions. By converting sunlight directly into electricity, they utilize an inexhaustible resource and produce virtually no greenhouse gases or air pollutants during operation. This significantly contributes to reducing carbon footprints and combating climate change.

Question 2

Which technology is most commonly used to generate electricity from wind?

Accepted Answer

Wind turbines

Answer

Wind turbines are the most commonly used technology to generate electricity from wind energy. These large structures feature aerodynamic blades that capture the kinetic energy of the wind, which then drives a generator to produce electrical power. Wind farms, consisting of many turbines, are a significant source of renewable electricity globally.

Question 3

What is the main advantage of geothermal energy?

Accepted Answer

It provides consistent and reliable energy output

Answer

The main advantage of geothermal energy is its ability to provide a consistent and reliable baseload power supply. Unlike intermittent renewable sources such as solar and wind, geothermal power plants can operate 24/7, largely unaffected by weather conditions or time of day. This makes it a highly dependable source of clean energy, crucial for grid stability.

Question 4

Which of the following best describes a net metering policy?

Accepted Answer

Allowing solar users to earn credit for surplus electricity

Answer

Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. When a solar system generates more electricity than the home or business uses, the excess power is sent back to the grid, and the customer receives a credit on their utility bill. This policy incentivizes solar adoption by making it financially beneficial for consumers to generate their own power.

Question 5

What is a typical challenge with wind power?

Accepted Answer

Wind availability is not consistent

Answer

Wind power is inherently intermittent because wind speeds fluctuate naturally and are not always present when electricity is needed. This variability makes it challenging to integrate large amounts of wind energy into the grid without robust energy storage solutions or backup power sources. The inconsistent nature of wind requires careful grid management to maintain a stable power supply.
